Find the remainder R by long division and by the Remainder Theorem.

(2x4 - 10x2 + 30x - 60) : (x + 4)

Select the appropriate response:

A) f (-4) = 6 (-4) ^4 - 10 (-4) ^2 + 30 (-4) - 60 = 200

B) f (-4) = 2 (-4) ^4 - 10 (-4) ^2 + 30 (-4) - 60 = 172

C) f (-4) = 2 (-4) ^4 - 10 (-4) ^2 + 30 (-4) - 60 = 142

D) None of the above

B

Step-by-step explanation:

To find it you do you divide by x+4=0 so - 4 plug in - 4 and get 172 so B

Melody Reeves · Answer 2

B) f (-4) = 2 (-4) ^4 - 10 (-4) ^2 + 30 (-4) - 60 = 172

Step-by-step explanation:

(2x4 - 10x2 + 30x - 60) : (x + 4)

x = - 4

Remainder:

2 (-4) ⁴ - 10 (-4) ² + 30 (-4) - 60 = 172
